I'm thinking a lot last days which new tele-toto lens to buy since I found my 70-200 is not enough for any serious picturing in mountains (wild animals).
And now I found big problem since there are many lenses in market around 400mm so I just can't decide what to choose, and what lens is best..
Since I have 70-200mm (+1,4TC and 2.0TC) I remove all lenses up to 300mm because I can get to that range with 1.4x TC) and I mostly focus on 400mm+ lenses. Here is my short list of what I find that can match my needs. Just to say my camera is 20D, and soon will be 40D.
Canon EF 100-400mm f/4.5-5.6L IS USM
Sigma APO 50-500mm F4-6.3 EX DG HSM
Canon EF 400mm f/5.6L USM
I was thinking about Canon EF 300mm f4.L IS USM + 1.4 crop factor but I find that quality of picture is lower then 400mm f5.6 so I remove it from list and if I ever need more then 400 then I need to put 2.0xTC and picture quality will be probably not good.
Thnx in advanced for your help..
I'm mostly looking for lens with I can shoot from hands since I will not have time to take my monopod from backpack. and usualy I will shoot during day. Of course Image quality is important too.
